BUFFlNG-WHEEL.

sl'EGIFICATION forming part of Letters Patent No. 713,201, datedNovember 11, 1902.

' Application filed August 8, 1902. Serial No. 118,844. (No model.)

To aZZ whom, it away concern:

Be it known that I, EGBER'I REED BURNS, a citizen of the United States,and a resident of Brooklyn, in the county of Kings and State of NewYork, have invented certain new and useful Improvements inBuffing-WVheels, of which the following is a specification.

The invention relatesv to improvements in buffing-wheels; and itconsists in the novel features, arrangement, and combination of partshereinafterdescribed, and particularly pointed out in the claims.

The object of the invention is to produce a buff-wheel possessingsuperior qualities and having a firm central portion and a looseflexible peripheral portion, the body of the wheel being formed of twoexterior disks, a series of spirally-arranged smaller disks held betweenthe center and the periphery of the two outside disks, and a stiff-coreportion at the center of the wheel, the said outer disks,

spirally-arranged disks, and core portion be-- ing firmly securedtogether by lines of sewing extending transversely through the wheel andengaging the component parts thereof.

The invention will be fully understood from the detailed descriptionhereinafter presented, reference being had to the accompanying drawings,in which Figure 1 is a side elevation of a buffingwheel constructed inaccordance with and embodying the invention. Fig. 2 is a centralvertical section of sameon the dotted line 2 2 of Fig. 1. Fig. 3 is anelevation of the buffing-wheel with one ofthe outer disks removed, so asto disclose the spirally-arranged inner disks; and Fig. 4 is a detachedelevation of one of the core-pieces for stifiening the central portionof the wheel.

In the drawings, 10 1O denote the two outer large plain disks for thewheel, these disks by their size determining the full diameter of thewheel and constituting the opposite sides of the same. Between the sidedisks 10 10 are arranged in spiral forma series of smaller disks 11, thelatter being about equal in diameter to about one-half of the diameterof the disks 10 and being arranged in a substantially uniform manneraround the center of said disks 10, as illustrated in Fig. 3. Asufficient number of the smaller disks 11 will be employed to produce awheel of the desired thickness. At the center of the wheel will beemployed a suitable core or stiffener for imparting a degree of rigidityto the central portion of the wheel, and in the present case I interposebetweenthe smaller disks 11 two cardboard disks 12 12, the latter beingcentrally of the wheel and considerably less in diameter than the wheel,as illustrated in Fig. 2.-

I have found that the loose flexible buffwheel constructed in the mannerdescribed, with the disks 1O 11, of cotton or filamentous material, andhaving a stiffener or core at its center, to be of great efficiency inpractical use.

The buff-wheel constructed in the manner described enables theemployment in its construction of what has heretofore beenpracticallywaste material, although I do notlimit the present inventionto the use of this waste material. Flexible butt-wheels have heretoforebeen made from a series of cotton disks placed against each other offrom ten to eighteen inches in diameter, and these wheels when worn downto about from four to eight inches'in diameter are considered to beuseless and are called hubs, which are thrown away. In accordance withmy invention I make use of the then smaller disks contained in theaforesaid hubs for the disks 11 of my wheel, the disks from the hubsbeing arranged spirally, as shown in Fig. 3,-between the large new disksl0 and having embedded within them'at the center of the wheel astifiener, such as the cardboard disks 12, the whole, as illustrated,being secured together by lines of sewing 13. It is not necessary thatall of the lines of sewing 13 shall pass through the stiifener-disks 12,it only being necessary that the disks-12 shall be firmly held. Thelines of sewing 13 secure the disks 1O 11 12 firmly together at thecentral portion of the wheel, and the outer edges of the disks 1O 11constitute the periphery of' the wheel,

and when the whole is constructed a loose flexible buff-wheel having afirm center is produced.

In Fig. 2 I illustrate diagrammatically a spindle 14, having clampingheads or plates 15 for holding the buff-wheel and imparting to it itsproper rotation; but the invention is not limited to any special meansfor holding or rotating the wheel, said wheel constituting in itself anew article of manufacture andusually having a central opening toreceive the spindle upon which it may be placed.

In the foregoing description I have presented the preferred constructionof the buffingwheel; but it is to be understood that I do not confinethe invention to a technically spiral arrangement of the disks llencircling the center of the disks 10, since the main object in thisregard is that the disks 11 shall overlap each other in series and be soarranged around the center of the disks 10 as to form a wheel ofsubstantially uniform thickness.

hat I claim as my invention, and desire to secure by Letters Patent, is-

1. The buff-wheel comprising the outerside disks, the series of smalleroverlapping disks arranged between and intermediate the center andperiphery of the said side disks, and a central stiifener or core forimparting a requisite rigidity to the center of the Wheel; substantiallyas set forth.

2. The buff-Wheel comprising a body portion made up of the series ofcircularly-arranged overlapping disks 11, and a central stifiener orcore, the whole being secured together around the center of the wheel;substantially as set forth.

Signed at New York, in the county of New York and State of New York,this 7th day of August, A. D. 1902.
